Hi Andy, in trying to set up a prepare-enabled staging system in Padova we found problems in using the xrootd.prep directive. Here, the server refuses to accept any value for it saying that the directory does not exist (even things like /tmp). Roberto spotted this small bug in XrdXrootdConfig.cc, after the correction the server now starts but the prepare request still does nothing. I put here the small fix and our test xrootd.cf file, please could you have a look at it to see if we forgot to set something to put the prepare at work? BTW the normal staging works fine! Thank you Fabrizio Index: XrdXrootdConfig.cc =================================================================== RCS file: /afs/slac.stanford.edu/g/babar/repo/xrootd/src/XrdXrootd/XrdXrootdConfig.cc,v retrieving revision 1.37 diff -r1.37 XrdXrootdConfig.cc 776c776 < || (rc = XrdXrootdPrepare::setParms(buff)) < 0) --- > || (rc = XrdXrootdPrepare::setParms(ldir)) < 0) config file: --------------------------------------------------------------- odc.manager bbr-xrootd.pd.babar 3121 xrootd.trace all xrd.trace all all.adminpath /opt/xrootd/admin olb.adminpath /opt/xrootd/admin # The Open Distributed Cache Section # # The Open Load Balancer Section # olb.trace all olb.allow host bbr-xrootd.pd.babar olb.allow host bbr-user02priv.pd.babar olb.allow host bbr-cndserv03.pd.babar olb.allow host bbr-datamove*.pd.babar olb.port 3121 #olb.path w /store olb.path w /prod olb.path ws /xtc # olb.path w /xtc # olb.path w /ERToMerge # olb.path w /ERToExport olb.sched cpu 10 io 90 olb.perf int 3m pgm /opt/xrootd/etc/XrdOlbMonPerf 180 olb.subscribe bbr-xrootd.pd.babar 3121 olb.wait olb.role server olb.prep echo scrub 30s keep 12h ifpgm /opt/xrootd/utils/mps_prep -c /opt/xrootd/etc/xrootd.cf # The Open File System Section # ofs.redirect target # The Open Storage System Section (cache & localroot are used by olb) # # oss.stage oss.trace all #oss.mssgwcmd /tmp/stage.pl #oss.stagecmd | /tmp/stage.pl oss.nocheck oss.nomig oss.alloc * * 80 oss.cache public /kanga/d1/xrootd/prod oss.cache public /kanga/d2/xrootd/prod &oss.cgroup xtcgrp &oss.sprty 3 #oss.cache xtcgrp /kanga/d1/xrootd/xtc #oss.cache xtcgrp /kanga/d2/xrootd/xtc #oss.cache prod /kanga/d1/xrootd/prod #oss.cache prod /kanga/d2/xrootd/prod # oss.cache public /kanga/d1/xrootd/ERToMerge # oss.cache public /kanga/d2/xrootd/ERToMerge # oss.cache public /kanga/d1/xrootd/ERToExport # oss.cache public /kanga/d2/xrootd/ERToExport oss.fdlimit * max oss.localroot /data/xrootd #oss.remoteroot /babar #oss.path /store oss.path /xtc stage mig oss.path /prod nostage nomig # oss.path /xtc # oss.path /ERToMerge # oss.path /ERToExport oss.mssgwcmd /opt/xrootd/utils/tinacmd.pl oss.stagecmd /opt/xrootd/utils/mps_Stage -dv -F -k -c /opt/xrootd/etc/xrootd.cf oss.xfr 8 30M 5m 0 # The XRD Section # xrd.protocol xrootd * xrd.timeout idle 999h # The XROOTD Section # xrootd.fslib /opt/xrootd/lib/libXrdOfs.so #xrootd.export /store xrootd.export /prod xrootd.export /xtc # xrootd.export /ERToMerge # xrootd.export /ERToExport xrootd.async off xrootd.chksum crc32 /opt/xrootd/etc/getCRC32.sh xrootd.prep logdir /tmp/preplog mps.adminuser bbrprmgr #mps.basedir /store mps.debug 4 #mps.errlogfn /data/xrootd/logs/mpslog #mps.errlogintvl 60 #mps.ftpcmd /opt/xrootd/utils/xfrcmd mps.keyfn /var/adm/mps/xfrcmd/keyfile #mps.lockfn DIR_LOCK #mps.migr.logfn /var/log/mps/mlog #mps.pstg.logfn /var/log/mps/slog #mps.purg.logfn /var/log/mps/plog #mps.stage.logfn /var/log/mps/Slog mps.mailcmd /bin/mail #mps.prtyfn /var/mps/migrpurg mps.max_retry 2 #mps.migr.max_retry 2 #mps.mssdir /store mps.migr.waittime 2419200 mps.pstg.waittime 1 mps.purg.waittime 2419200 mps.xfrblksz 1024 mps.xfrhost bbr-tape mps.xfrport 21 mps.xfruser bbrprmgr mps.stage.cpgroup xtcgrp mps.scan /data/xrootd mps.cache xtcgrp /kanga/d1/xrootd/xtc mps.cache xtcgrp /kanga/d2/xrootd/xtc mps.mssstat = stat mps.xfrcmd = /opt/xrootd/utils/tinaxfr.pl %sfn %tfn # For pre-stage, we generally want to indicate the maximum number allowed # at one time and the command to use to transfer data from the mss # mps.pstg.max_pstg_proc = 3 #mps.pstg.pstgcmd = /opt/xrootd/utils/mps_PreStage -i -x 3 -c /opt/xrootd/etc/xrootd.cf mps.pstg.pstgcmd = /opt/xrootd/utils/mps_prep -x 3 -c /opt/xrootd/etc/xrootd.cf mps.pstg.stopstg /tmp/STOPPSTG
